Answer :
Final answer:
Friction, while generally a force that opposes motion, is an essential component in various mechanical systems such as pistons in a cylinder, car brakes, drilling machinery, clutch engagements, and even grinding machines. In these contexts, the frictional force enables efficient operation of the systems, underscoring the important role that friction can play.
Explanation:
Friction is a force that opposes relative motion between systems in contact. However, in certain cases, such as the options provided in the question, friction is actually crucial for the mechanism to effectively function. Let's examine the examples to understand how this works:
- A. Movement of piston in a cylinder: In a piston-cylinder arrangement, friction is desirable as it helps in the creation of a sealing effect which prevents the escape of gases, ensuring efficient operation.
- B. Car brakes: The friction between the brake pads and the wheel drum is what allows the car to slow down or stop when the brakes are applied. Without this frictional force, the car would continue to move.
- C. Drilling operations: Friction is what allows the drill bit to penetrate surfaces. Without friction, the drill bit would simply rotate uselessly on the surface without making any headway.
- D. Clutch engagement in vehicles: Engaging the clutch in a vehicle requires friction in order to transmit power from the engine to the drivetrain.
- E. Grinding machinery: Friction is crucial in grinding machinery as the movement of the abrasive against the material to be ground results in the removal of material.
Therefore, although friction often opposes motion, thereby potentially dampening efficiency, it is certainly desirable and necessary in numerous practical applications.
